Eric Mendez Status Report October 26

This week I tested the Bluetooth of the raspberry pi and found it to be rather difficult to use. Especially if I was going to use it to connect the speaker. We are now using NRF24L01 chips which communicate through radio frequencies instead of Bluetooth, and hopefully, that will help simplify our staff communication code. I also got the display and gpio extenders for the raspberry pi so we have access to 80 pins instead of 40. We ordered this because the screen takes about 20 pins on the gpio. I also worked on creating concurrent programming for the speaker, so the code would fork(), the sound would play, and the main loop would keep searching for inputs until that sound process exited. The main process then cleans up the code using a sigchld_handler similar to the one I implemented in my 15-213 shell lab code from a previous semester. I haven’t quite worked out all the bugs, but I’m going to be debugging the baseline game code so we can start messing with the circuit Dan is going to create for testing. I also cleaned up the game flow code so that we would be able to receive inputs from buttons in the circuit and would be able to create an abbreviated output using the vibrating motors.
